摘要
双酚是一组种类繁多的干扰内分泌的化学品 (EDC),它们会影响荷尔蒙的活性。双酚 F (BPF) 通常被用作双酚 A (BPA) 的替代品。在胚胎大脑发育过程中,EDCs 对免疫系统的破坏被认为是导致神经发育障碍的一个可能因素。我们研究了围产期暴露于 BPF 对后代小鼠神经毒性的影响。雌性小鼠在怀孕的第 0.5 天开始通过饮用水接触 BPF,这种接触一直持续到后代小鼠断奶,贯穿整个围产期。我们的研究结果表明,暴露于 BPF 会阻碍后代小鼠的生长和神经发育,对雄性小鼠的影响更为明显。此外,我们还对暴露于高剂量 BPF 的雄性后代小鼠的大脑进行了转录组分析。总之,我们的研究表明,围产期暴露于 BPF 会导致雄性后代小鼠神经发育受损,这与氧化应激、炎症反应和免疫失调有关。这些发现突出表明,BPF 可能不是双酚 A 的安全替代品。因此,迫切需要重新评估目前对 BPF 的监管。
Neurotoxic effects of perinatal exposure to Bisphenol F on offspring mice
Bisphenols constitute a diverse group of endocrine-disrupting chemicals (EDCs) that impact hormone activity. Bisphenol F (BPF) is commonly used as a substitute for Bisphenol A (BPA). The disruption of the immune system by EDCs during embryonic brain development has been suggested as a plausible factor to neurodevelopmental disorders. We investigated the neurotoxic effects of perinatal exposure to BPF on offspring mice. Female mice were exposed to BPF through their drinking water on day 0.5 of pregnancy, and this exposure continued until the offspring mice were weaned, throughout the perinatal period. Our findings revealed that exposure to BPF hindered both growth and neurodevelopment in offspring mice, with a more pronounced effect observed in males. Additionally, transcriptomic analysis was conducted on the brains of male offspring mice exposed to high doses of BPF. In summary, our study indicates that perinatal exposure to BPF results in neurodevelopmental impairments in male offspring mice, linked to oxidative stress, inflammatory responses, and immune dysregulation. These findings underscore that BPF may not be a safe substitute for BPA. Thus, there is a pressing need to reevaluate the current regulation of BPF.
期刊介绍:
Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health.
Subject areas include, but are not limited to:
• Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies;
• Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change;
• Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects;
• Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects;
• Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest;
• New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
